Research on Voltage Stability Analysis Methods and Control Technologies for Power System

电压稳定性可以分为短期电压稳定性和长期电压稳定性。短期电压稳定性涉及电力系统在数秒至数分钟内应对突发扰动的能力,长期电压稳定性则关注电力系统在数分钟至数小时内对缓慢变化的负荷或电网结构变化的适应能力。若电压缺乏稳定性,则会导致大范围停电事故。因此,研究电压稳定性分析方法和调控技术对于保障电力系统的安全运行具有重要意义。传统电压稳定性分析方法和调控技术在应对复杂多变的电力系统运行环境时,存在一定的局限性。随着电力电子技术、计算机技术以及大数据技术的迅猛发展,新的技术不断涌现,为电压稳定性研究提供了新的思路和手段。文章旨在系统地探讨电力系统电压稳定性分析方法和调控技术,通过优化策略的设计和实施,提高电网的电压稳定性,确保电力系统的安全、可靠运行。

Voltage stability can be classified into short-term voltage stability and long-term voltage stability.Short-term voltage stability involves the ability of the power system to respond to sudden disturbances within seconds to minutes,while long-term voltage stability focuses on the power system’s ability to adapt to slowly changing loads or changes in grid structure over minutes to hours.If voltage stability is lacking,it can lead to widespread blackouts.Therefore,researching voltage stability analysis methods and control technologies is of great significance for ensuring the safe operation of power systems.Traditional voltage stability analysis methods and control technologies have certain limitations when dealing with complex and changing power system operating environments.With the rapid development of power electronics technology,computer technology,and big data technology,new technologies are constantly emerging,providing new ideas and means for voltage stability research.This paper aims to systematically explore power system voltage stability analysis methods and control technologies,improve grid voltage stability through the design and implementation of optimization strategies,and ensure the safe and reliable operation of power systems.
